The Pearson correlation coefficient (also known as Pearson’s r) and Spearman’s rank correlation are the most widely used correlation coefficients [2]. However, there are many others including intraclass correlation and Moran’s I. If you’re just beginning elementary statistics, you’ll most li...
The spillman rank correlation coefficient of random variable X and Y can be calculated by X, Y or d, and the calculation method is as follows: It is calculated by the ranking difference set d (formula 1) : Calculated by the ranking set x, y, and (spearman rank correlation coefficient,...

The Spearman’s rank coefficient of correlation or Spearman correlation coefficient is a nonparametric measure of rank correlation (statistical dependence of ranking between two variables). Named after Charles Spearman, it is often denoted by the Greek letter ‘ρ’ (rho) and is primarily used for ...
